Just to add. I don't give my dwarf hamster sweets because that's not good for her. I feed her a small scoop of dwarf hamster mix daily, a pinch of brown linseeds and a very small amount of greens like spinach, peas, kale, broccoli, cucumber etc but no fruit because of the sugar. For a treat she gets a few dried mealworms or sunflower seeds and she has a whimzee.

Your hamster probably put on weight because you fed him sweets every day but he's your first hamster and we all had to learn and we are still learning, so don't worry about it.

Maybe have a chat with your mum and teach her about the different hamsters and that Syrians are a lot bigger and heavier than dwarf hamsters.
